An Insensitive Munitions safety device mitigates the occurrence of a violent response of an anti-armor munition subjected to elevated temperatures. The anti-armor munition includes a projectile body having fore and aft ends, an explosive charge disposed in the projectile body, and a projectile-forming or jet-forming liner disposed in the projectile body. The liner includes an aft surface contiguous with the explosive charge and a fore surface that defines a void. A liner restraint abuts a fore end of the liner and restrains movement of the liner. A portion of the liner restraint comprises a material having a heat deflection temperature less than the critical temperature of the explosive charge in the munition.

A single multipurpose ammunition projectile/warhead is provided, which has the capability of clearing a variety of different types of hardened targets. The single projectile of this invention may be used for breaching steel reinforced concrete walls; may be used against light armor targets; may be used for defeating bunkers; and may also be used for antipersonnel applications. Huge savings in time, money, inventory and logistics are realized through utilizing only this one multipurpose ammunition against all these types of targets. This multipurpose projectile, among other superb capabilities, is able to puncture an eight inch double steel reinforced concrete wall timed to then have its warhead explode into fragments. This allows fragmentation in a more effective, nearly ideal direction. The projectile warhead of made of extremely thick walled 300M steel; with the projectile center of gravity to be located equidistant between a pair of bourrelets, for increased stability.
